Ever try to give your husband directions from the passenger seat? This may seem like nothing—after all, you’re just trying to be helpful!—but it can have a damaging effect on your sex life. “Men hate being told what to do, especially in the car,” says Fran Walfish, Psy.D., a psychotherapist in Beverly Hills, CA. It can also bring your guy down if you RSVP to a party without asking his thoughts or mock his abilities, even if you’re joking. “When your partner is angry, he’s likely to either snap at you or become silent,” adds Walfish. “And when communication goes south, sex is a natural follower.”

Be honest: When’s the last time you slipped on that lacy lingerie your husband loves? Chances are it’s at the bottom of your drawer, underneath more comfy options like cotton sweats and tank tops. That makes sense—you’re exhausted when you finally get to your bedroom, and you may not feel as sexy as you once did in a negligee. But more so than women, men are turned on by sight—regardless of whether you weigh five pounds more than you did five years ago, says John Wilder, a marriage, relationship, and sexual coach in Jacksonville, FL. If you aren’t at home in some overly skimpy—and often pricey—lingerie, simply wearing your favorite T-shirt and nothing but nice underwear on the bottom will show off your legs and get your guy excited.
